Surface Enrichment of Pt in Stable Pt-Ir Nano-alloy Particles on MgAl2O4 Spinel in oxidizing atmosphere

Abstract

With the capability of MgAl2O4 spinel {111} nano-facets in stabilizing small Rh, Ir and Pt particles, bimetallic Ir-Pt catalysts on the same support were investigated, aiming at further lowering the catalyst cost by substituting expensive Pt with cheaper Ir in the bulk. Small Pt-Ir nano-alloy particles (
